The globe is divided into specific regional zones. For example, K is reserved for the contiguous United States, C for Canada, E for Northern Europe, and V for parts of Southern Asia.
Unlike the more common 3-letter IATA codes used on commercial luggage tags (e.g., JFK, LHR), ICAO codes are 4-letter codes constructed logically to help pilots and dispatchers identify exactly where a facility is in the world.

As the aviation industry continues to evolve, it is essential that Doc 7910 PDF is reviewed and updated regularly. Future directions for the document may include:
Each location indicator is used as the base address for every service at that location. Additional letters are appended to the four‑letter base to specify a particular function (for example, a control tower, a weather service, or an air traffic control centre), with the rules for those suffixes laid out in a separate ICAO document, Doc 8585.
